ABSTRACT:
A telephone set includes a coiled multi-conductor cable connected to an assembly such as a handset by a standard modular connector and an appliance is interposed in the connector to inhibit twisting of the cable. The appliance includes two parts which freely rotate relative to each other with one part receiving the male element of the connector and the other part being inserted into the female element of the connector so that, rather than the cable twisting, the parts of the appliance rotate relative to each other. The electrical connection between the conductors in the cable and conductors in the handset is maintained by cooperating contacts on the other part and on the female element and by wipers carried by one of the parts and engaging conductive rings on the other part.
